Curtains

Avoid exposing your curtains to direct sunlight where possible. (Curtain linings and blinds help).
Vacuum occasionally to remove dust.
Protect curtains from excess humidity. Keep away from moist walls and windows and keep windows closed during rainstorms and lawn watering!
Rotate curtains whenever possible to equalise the effects of bright sunlight.
Have your curtains cleaned at least every two years to keep colours clean and bright and to extend their life.
